Door chime problem

My door chime started buzzing; I disconnected the transformer wire to stop it temporarily. Installed a new transformer and chime unit. No more buzzing, the back door chime works fine (1 chime), but the front door chime dings once followed by a dull noise. Like "ding-clunk".

I see a piece of foam glued on the chime unit for one chime. Instructions don't mention the foam so I assume it's to keep the back door from chiming twice. BTW the chime came as a unit, so the transformer is matching. What's the problem?

Either there is a chime bar (tone bar) missing, blocked, or misaligned for the front door solenoid. Or, the spring that is designed to make it kick back to hit the second plate could be missing or broken.

Open it up and have someone operate it while you watch the chime and its solenoids.

Funny how they don't make shet like they used to. My Mom's doorbell transformer (NuTone) is 48-years-old and it still works.

In fact, the only service to the entire unit has been to replace the doorbell switches because the light bulbs blew out. And I believe the O.E.M. lights lasted more than a decade before they went ****-up.

Our transformer (Heath, made in China) has already died once and it's less than four years old. I've also replaced the doorbell switch three times in as many years due to bulbs that keep blowing out.

One of the advantages of being an EE, I have replaced the lights in my doorbell switches twice! I've lived in this house for 44 years, boy those lights work for a long time! I'm impressed.
